In Gangster Alley you are looking with a crime-ridden building from behind the crosshairs of your gun. When a gangster pokes his head out of a window, you must shoot him before he has a chance to draw a bead on you and destroy one of your four bulletproof vests.
You receive a cash reward for each gangster you kill. But be careful -- there are plenty of innocent civilians who live in these buildings, too. Hit one of them and you lose money. Nitro Ed, the big boss, roams back and forth at the top of the building. You can't kill him, but go after him for big points and when you see he is about to drop a grenade. Gangster Alley ends when all of your vests are lost, or when Nitro Ed successfully unleashes a grenade. Extra vests are awarded for every $5,000 you earn.
